I think that the problem was that we didn't go all in but left a "back door" in case it didn't take, and of course it didn't. As for the building trades, you wouldn't need to change the size of dimensional lumber, just how it's measured. Let's face it, houses and buildings aren't crashing down because the things we call 2x4s are not 2" by 4"...
